Interesting animal, though I prefer kentrosaurus myself. That might just be a bias because of my younger years spent watching the Dino Riders cartoon, though. Regardless, these animals are very neat. I often wonder what it was that pushed them to evolve the spikes rather than the wide plates sported by animals like stegosaurus. Plus, kentrosaurus has those fantastic shoulder spikes sticking out too. It's just such a unique critter. Great work!
